SWITCH.

Application filed February This invention relates to switches and moreparticularly to tongue switches, and has for its object the provision ofa novel means for holding down the point of the switch tongue.

Another object is to provide holding down mechanism which will beapplicable to standard trailing point switches where the standard springor lock mechanism is not required, and yet it is desirable to hold thetongue point to the bed of the switch to pre vent excessive wear andkeep the tongue in the worn switch bed from excessive noise duc to itjumping about Aand in extreme cases from jumping out of place due to theforce of traffic passing over it.

A further object is to provide a. switch having the novel design,construction and combination of parts hereinafter described in thefollowing specification and illustrated in the accompanying drawings:

ln the drawings Figure 1 is a plan view of a portion of a standardtongue switch having my invention applied thereto.

Figure 2 is a sectional elevation on the line II-H of Figure 1.

Figure 3 is a view similar to Figure 1 showing a modified embodiment ofmy invention.

Figure 4 is a sectional elevation on the line lV-IV of Figure 3. 4

Referring more particularly to the drawings the numeral 2 designates theswitch body, which is provided with a longitudinal groove or recess 3forming a tongue bed, to receive the switch tongue 4.

The switch vtongue 4 is provided with a downwardly extending lug 5 at apoint intermediate its ends, which lug is apertured at 6 in a directiontransversely of the longitudinal axis of the tongue.

A standard spring box 7, such as is ordinarily used to house the springoperating r mechanism of a trailing switch, is secured by bolts S to theswitch body 2 and the switch body 2 and box 7 are apertured to form apassage 9.

A casting 1() having spaced vertically extending ears 11 is secured inthe box 7 by the bolts 8. A. crank lever 12 is pivotally mounted betweenthe ears v11 by a pivot pin 14. The forward 'arm 15 of the crank leveris slotted longitudinally at 16 to receive a holding down bar or rod 17The other or rear arm 18 of the crank level` is apertured.

1e, 1926. serm- No. 88,637.

at 19 to receive the downwardly bent rear end 2O of the bar or rod 17.The rear arm 1S of the crank lever is provided adjacent its rear endwith a vthreaded aperture 21 in which is threaded an adjusting screw 22adapted to be threaded through said aperture and bear against thecasting to rock the crank lever about the pivot pin-14.

The rod or bar 17 has its forward end mounted in the aperture 6 of thelug 5 and said lug is adapted to move along said rod as the switchtongue is moved from side to side of the groove or bed 3 of the switch..body 2.

A stiifener tube 24 is mounted on the rod 17 to stifi'en and strengthenit against bending strains.

In operation, after the parts are assembled the screw 22 is threadedthrougl'r the aperture 21 in the arm 18 of the crank lever thus forcingthe arm of the crank lever downwardly against the rod 17 and in turnforcing the rod 17 downwardly against the lug 5 so as to hold the tongue4 in its bed 3.

If it is desired to remove the rod 17 for any reason it is onlynecessary to remove the screw 22 and withdraw the rod into the box 7 andthen tilt it upwardly until it clears .the box and then remove it, thepassage 9 being of suicient size to permit this tilting of the rod 17.

In the modied construction of Figures 3 land 4 a telescoping holdingldown rod or bar 17a is provided for holding down the tongue. The rod 17ais composed of a solid bar portion 25 adapted to be slidably fittedwithin the aperture 6 in the lug 5, a tubular portion 26 welded to thebar portion 25 and extending through the passage 9, and a second barportion 27 telescoped within the tubular portion 26v and removably heldin position by a pin' 28 which extends downwardly through the tubularportion 26, the bar 27 and flange 29 of a casting 10 which issubstituted for the casting 10 of the preferred embodiment of myinvention.

The rear end of the bar portion'27 is enlarged to form a head 30 whichis apertured -to receive a bolt 31, which bolt extends downwardly into asquared recess 32 in the casting 10a and is threaded in a nut 33 mountedin said recess. The nut 33 is slidably mounted in the recess 32 and heldagainst rotation by the walls thereof. A coil spring 3 4 is mountedaround the bolt 31 between the' head 30 of the bar and nut ecy 33 sothat by threading the bolt 3i. through the nut 33 the spring will becompressed.

.i locking ring 35 is iitted over the head ot the bolt 3l and isprovided with lugs 36 which engage the bar 27 to prevent rotation ot'the bolt 3l and ring.

The castingl0n extends upwardly along the sidewall oi the box 7 next tothe switch body and is apertured at 38 to permitthe rod 17 to enter tiepassage 9 .termed by the apertures in the bof: Y and the switch bodyThe, tace ot' the casting above the aperture 3S is rounded to form atulcrum bearing` tor the rod 17.

in operation, when the ports are assembled, the bo t "ll will bethreaded downwardly through the nut 33 tous compress ing the spring 3land 'forcing' the rod i7 against the iulcrum bearing` 39 and cause ing`the forward end oi the rod to apply a downward force against the lug 5of the tongue Due to the spring 341 between the nut 33 and rod l?l thetorce applied to the rod will be yieldable and, theretore, considerabletorce may be applied to the rod 17 and tongue wit-hout bending the rodor binding the switch tongue lli/*hen it is desired to remove the rod 17for repairs or renewal, the pin 2S is removed, the locking ringv 35 isremoved, end the bolt 3l is then unt-hrea-oed .trom the nut so as topermit removal oi the bolt and spring` rlhe bar portion 27 is thentelescoped within the tubular portion 2G, and the telescoped rod 17a isthen moved rearwart ly within the bof; .7 and 'tilted upwardly so as toclear the bon.

`Vilhile l have shown and described eertain specitie embodiments of myinvention it will be understood that l do not wish to be limitedthereto, since various modifications may be made without departing fromthe scope ot my invention as dei'ined in the appended claims.
